Leupeptin acid

Leupeptin acid is a peptide byproduct present in the fermentation product of Streptomyces roseus MA839-A1, and also an intermediate in leupeptin biosynthesis. Leupeptin acid serves as a substrate for leupeptin acid reductase to generate Leupeptin (HY-18234).

Protein/Amino Acid Metabolism

Leupeptin acid is reduced to Leupeptin (HY-18234) by solubilized leupeptin acid reductase from Streptomyces roseus MA839-A1 in an ATP- and NADPH-dependent manner; the enzyme has K_m values of 4.2 × 10^-5 M for ATP and 1.3 × 10^-6 M for NADPH, and is strongly suppressed by leupeptin and antipain rather than elastatinal^[2].
Leupeptin acid is biosynthesized as an intermediate to form leupeptin by the combined leucine acyltransferase and leupeptin acid synthetase-reductase complex from Streptomyces roseus MA839-A1 using acetyl-CoA, L-leucine (HY-N0486) and L-arginine (HY-N0455) as substrates^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
